% \framesubtitle{} 
\begin{itemize}

{\small
    \item \textbf{Raw Data File}: A file consisting of rows and columns of numbers; or maybe some of the columns have letters (character data) instead of numbers. The rows represent observations and the columns represent variables. \pause Can be plain text or in a spreadsheet. \pause
 
    \item \textbf{Program File}: A file consisting of commands that the SAS software tries to follow. You create this file with a text editor. The program file contains a reference to the raw data file, so SAS knows where to find the data. Program files have names like \texttt{reading1.sas}. \pause

    \item \textbf{Log File}: This file is produced by every SAS run, whether it is successful or unsuccessful. It contains a listing of the program file, as well any error messages or warnings. It will have a name like \texttt{reading1.log} or \texttt{reading1-log.html}.\pause
 
    \item \textbf{Results File}: The list file contains the output of the statistical procedures requested by the program file.  Output files have names like \texttt{reading1-Results.pdf}, \texttt{reading1-Results.rtf}, or \texttt{reading1-Results.html}.

%\framesubtitle{} 
We will run SAS online using a web browser. \pause
\begin{itemize}
    \item Download data file from course website. Edit as needed. \pause
    \item Upload data file to SAS website. \pause
    \item Type SAS program into online editor. The program will contain a reference to the data file.\pause
    \item Run SAS. 
    \item Look at the log file. If there are errors or warnings, fix the program or the data file. You may need to edit the data file on your computer and upload it again. \pause
    \item Run SAS again, repeating until you are satisfied. \pause
    \item Download copies of the log file and the results file. Print for the quiz. \pause
    \item It would be smart to download a copy of your program too, as backup.

\begin{itemize}
    \item This is fairly new.
    \item It seems to be the full version.
    \item It's free of charge to anybody with a university email address.

    \item Create an account.
    \item They will send email with your user id. This takes a few hours.
    \item Go to \href{https://odamid.oda.sas.com}

\frametitle{Important Rule}
%\framesubtitle{} 
\begin{itemize}
    \item You may not use a classmate's SAS OnDemand account to do your work for this course. \pause
    \item It's too easy to see each other's program code. 
    \item You must have your own account. 
%    \item[] 
    \item If two people use the same account, they will both get zero for the assignment even if there is no academic offence.
